Introduction This invention relates to apparatus for the turning inside out of fabric tubes or bags, and more particularly to an apparatus for the turning of fabric belts or tabs of the tubular type as used in the manufacture of garments.

The turning of fabric belts or tabs of the tubular type after they have been cut and sewn, presents a considerable problem to the garment manufacturer, both in the cost of labour and the amount of time involved. When they are turned by hand, each tube has to be partially turned in and then pulled over a stick or form in order to reverse it, this operation necessarily consuming a great deal of time and thereby adding to the cost of the garment. The mechanical devices that are now available to perform this operation are mainl intricate and costly, and moreover, not sufficiently versatile to meet all the requirements of the clothing manufacturer using fabric belts and tabs in many sizes and types of materials.

The present invention deals fundamentally with these disadvantages and it aims to provide a thoroughly practical solution for them by providing a compact, portable, belt-turning apparatus adapted to turn fabric belts or tabs of practically any size or type of material as used by the garment trade.

Applicants development The invention is a tubular belt turning apparatus comprising a base, and at least one guideway extending from the base. An extension arm is slidably mounted on the guideway, and a plunger is attached to the extension arm. A guiding member attached to the guideway is adapted to guide the travel of the plunger. A turntable rotatably mounted on the base is adapted to carry a plurality of tubes of diiferent diameters. Registering means are provided on the turntable and base, whereby any one of the tubes is adapted to be stopped in register with the plunger.

According to a preferred and more specific aspect of the invention the apparatus includes, a base, a pair of rods attached to the base and extending preferably vertically therefrom. An extension arm is slidably mounted on the rods and a plunger attached to the extension arm. A supporting arm attached to one of the rods is adapted to guide the end of said plunger and has an opening through which the plunger may slidably move. A spacing bar attached to the rods at a point above the extension arm holds these rods apart substantially'parallel to each other. Resilient means are attached between the spacing bar and the extension arm to retain the arm in the inoperative position and raise the arm to its original position when said arm is depressed manually. A pair of stop bushings adjustably mounted on the other of the rods limits the amount of travel of the extension arm. A table rotatably mounted on the base is adapted to carry a plurality of tubes. The tubes are of different diameters to hold fabric tubes of various sizes for turning, and are so mounted on the table that a direct passage is provided for through the inside of the tube and a corresponding opening in the rotary table. A stop pin mounted in the base is adapted to register with a plurality of holes in the rotary table in order to stop each selected tube in register with the plunger. Suitable attaching means are used for the attaching of the apparatus to a bench or table as required.

Detailed description vation illustrating the method of employing the apparatus.

Figure 4 is an enlarged fragmentary side elevation illustrating the operation of the apparatus.

Referring particularly to Figure 1, a pair of rods I0 and I2, are secured to and extend vertically from a base 14 to a spacing bar It where they are secured substantially parallel to each other. An extension arm I8 is sliclably mounted on the rods II] and I2. The extent of the travel of the arm I8 is controlled by two adjustable stop bushings 20 and 22 mounted on the rod l2. A spring 24 is secured between the spacing bar l6 and the extension arm l8 and is adapted to retain the arm l8 in the inoperative position and to return the arm l8 to its original position on the arm I8 being depressed manually and released. A plunger 26 is secured to the extension arm l8, this plunger 26 being guided in its travel by a guide arm 28 mounted on the rod Ill. A spring 30 is mounted on the rod In above the guide arm 28 and provides a resilient buifer for the downward stroke of the extension arm [8. A table 32 is rotatably mounted on the base M by the rod id passing through a centrally disposed opening in said table 32. A plurality of tubes 34 of different diameters are mounted on the rotary table 32 in annular bosses 38. The bosses 33 surround holes in the table 32 of approximately the same diameter as the inside diameter of the tubes. The rotary table. 32 also, having a plurality, of holes 40 adapted to engage a pin 42 andstop in register any selected one of the tubes 34 with the plunger 26.

Operation The apparatus is mounted preferably vertically on a suitable bench or table. withathe'projectingportion of the table 32 extending overthe edge, or an opening, of the table or bench: so that a tubular belt or tab turned by the apparatus may be allowed to pass through the selectedltube-M' and fall into a convenient box or receptacle.

Gn turning a fabric'belt or.- tab-the appropriate size-of tube-34 is selected-to accommodate the belt. The-table: 32' is raised .slightlyonthe rod ill and rotated. till the required tube. 34 is. stopped. in register with the plunger. 2t by the stop. pin 42. Therbelt isthenipulled-over thetube SQ-(as-shown in Figure 3) and" the extension ar-m depressed manually, thusforcing the plungerZEinto. contact. with: the belt and" through the tube 34 (as shown in Figure 4).

It maybe understood bythe preceding; explanationv and. accompanying drawings, that if a belt'of a lengthexceedingthat-of the tube 34 and the: stroke ofthe plunger 26 is to be turned; the

extension" arm I-8-isdepressed=to the limit ofits I travel; thus. pushing sufficient or the belt through the tube 34 -so-that it may-be grasped-and pulled downwards manually to complete its turning. In the case-oflarge-quantitiesof short belts. or tabs of a length less than that of the-tube 34,, the extension arm may be depressed only as far as required tozturnithebelt,.thebelt thus remaining in the tube 34 till being pushed out by the successive turning of otherbelts;

As may be understood by the-preceding descriptionand' drawings, the simpledesign of this apparatus,- necessitating comparatively few working parts, lends itself to portability andcompactness'. Thecombination o'f'the rotary'table with thedifferent diameter tubes also providing an advantage over other'machin'es of this type in that substantially any size of tubular belt, or b'elts; made frompractically any type of material as used by'the garment trade; may be quickly and easily turned by this apparatus.

1. A tubular belt turning apparatus" including a base, a pair of rods attached" to said base; an extension arm slidably mounted on said rods, a

plunger attached to said extension arm, a guiding arm attached to one of said rods, said guiding arm having an opening adapted to allow said plunger to slidably move therein, a spacing bar connecting said rods, adapted to hold said rods in substantially equally spaced relationship to each other, resilient means attached between said extensionarm, and said spacing member, a pair of adjustable2stop bushings'mounted on the other of said rods, a turntable rotatably mounted on said base, a plurality of tubes mounted on said turntable, said tubes being of different diameters'; registering means on said base and table adaptedto stop said table so that the centre of the tubes and the plunger are in register, wherebysaid plungerl on; being depressed is adapted to engage-a fabric tube placed on any of said tubes in register.
